Teeth, teeth

The thing I missed most in Africa....................was my electric toothbrush.  But I went to the dentist recently (she's young, pretty and eastern European) and heard her as she counted round my teeth, comment 'toothbrush abrasion.' I asked her about it, she didn't know when it happened, but it could well be that I was scrubbing with the electric brush instead of letting it do the work itself. Now I have to concentrate NOT to brush my teeth.
